摘要：以多花黄精块茎为材料,分析不同林下生境和生长年限2个因素及其互作效应对多花黄精生长和药用活性成分含量的影响,运用隶属函数对各处理进行综合评价。结果表明:生长年限对多花黄精生长和药用活性成分含量的影响最大,对所有生长指标和药用成分含量指标的影响均达显著水平;林下生境对除苗高和地径外的其他指标影响均达显著水平。在双因素交互作用中,生境类型×生长年限的交互作用除对保存率影响不显著外,对其他指标的影响均显著。林下生境为毛竹林、生长年限为4 a组合的平均隶属函数值最大为0.938,其生长指标的隶属函数平均值为1.000,其药用活性成分含量指标隶属函数平均值为0.875,该组综合表现为所有栽培模式中效果最佳的组合。
Using fine yellow tuber as materials, this paper sets up a factorial design with habitats and growth years, and studies the interaction effects of these 2 factors on growth and medicinal active ingredient content of P.cyrtonema by applying the membership function to evaluating the cultivation mode effect comprehensively. The results are as follows: effects of growth years have the greatest impact on the growth and active medicinal ingredient content of P. cyrtonema, and reach a significant level on all growth indicators and medicinal component index;the impact of forest habitat is at lower level, but also significant on the removal of seedling height and ground diameter and all index effect. In the interaction of 2 factors, the interaction of habitat type and growth year was significant except for the preservation rate. The comprehensive evaluation of membership function shows that the combination of bamboo forest for the forest habitats and average growth years for 4 a reaches a maximum value of0.938 in membership function, 1.000 in the growth indicators of the membership function value, 0.875 in the average value of the medicinal active ingredient content index. The group reveals a best comprehensive effect in all cultivation patterns.
